Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration

Went to find Odysseus in his stone seat to seaward---tear on tear brimming in his eyes. The sweet days of his life time were running out in anguish over his exile‚ for long ago the nymph had ceased to please. …………………………………………………………………….. But when day came he sat on the rocky shore and broke his own heart groaning‚ with eyes wet scanning the bare horizon of the sea. (45-49‚ 52-54) This quote from The Odyssey written by the Greek poet named Homer expresses Odysseus’ pain. Homer is known to

Richardson Lab: Measuring the Density of Pennies Pre-Lab Questions: 1. The equation that relates density‚ mass‚ and volume is: density = mass / volume. 2. All substances have unique densities‚ so if you are able to find the density of a substance‚ you can properly identify it. 3. We measure irregular-shaped objects with the use of water displacement because it would be nearly impossible to get the exact measurements of items with irregular shaped surfaces manually. 4. It is important

Title: Finding the Ratio of Mole of Reactants in a Chemical Reaction Purpose of Lab: To find the coefficients of two chemical reactants that appears in a balanced chemical equation using the continuous variations method. Pre Lab Questions: 1. 2AgNO3(aq) + K2CrO4(aq) → 2KNO3(aq) + Ag2CrO4(s) 2. There is enough to make a valid conclusion because‚ on the graph‚ one can clearly see that the two lines intersect. Thus‚ one can also determine the mole ratio. The mole ratio is approximately

complete a 25 page manuscript‚ which including 5 pages of caveats. Recently‚ the editor requested me to limit the manuscripts to 20 pages. It is impossible to shorten other places. As the auditor of manuscripts‚ I am in a dilemma. I am considering whether to eliminate 5 pages of caveats or not. If I choose to satisfy editor’s requirement and cut 5 pages of caveats‚ I may face the result of possible misunderstanding from readers. Appropriate findings and caveats are important to the interpretation
